Question
Hello Dr. Clark,

I overheard an expert on a radio program saying that Iran has already stated it wants to destroy Israel & the U.S. & it's a matter of time until Iran or some other evil nation will use a nuclear weapon against us. He discussed that the electromagnetic wave from a certain size nuclear device detonated 100 miles above the U.S. could completely knock out much or all of our communications capability.
Are there any Biblical scriptures supporting America or Israel launching a nuclear first strike against our enemies if we know they're going to attack first in a matter of time? Does the Bible indicate anywhere that we would be going against God's law by killing innocent civilians in such an attack?
I would think God would support our first strike option if we go by Old testament law. New Testament law seems a bit different. Christ comes and seems to move us to love our enemies and even "turn the other cheek".
What might be your opinion on all of this?

Thank you very much.

Sincerely,

Mike Eidson

Answer
Mike, Catholic teaching includes the notion of the "Just War." Basically it stipulates that if a grave threat is at hand and all reasonable attempts to resolve the issue peacefully have failed, then legitimate self defense of a nation is permissible. Here's a fuller explanation:

Of course, each situation is different and the particulars of your question could be debated for months before coming to a solution. In real life, the exigencies of life (and staying alive) might not always give a nation months to consider.

But please don't interpret my providing this link as a direct answer to your question. I'm not qualified to analyze a political situation like that. I can only provide the general Catholic teaching about the so-called "Just War."
